Gas Supply Requirements
•
Gas supply type MUST match the type of gas shown on the rating plate.
•
Gas supply pressure must NOT exceed 14” water column (1/2 psi), and fall within the
pressure range shown below when using 3/4” NPT line and a 1/2” NPT connection
o
Na
tural gas pressure at 1000 BTU/CF must be 5 1/2” – 14” water column.
o
Propane gas pressure must be between 11” – 14” water column.
•
If the gas or propane supply pressure exceeds 14” water column, a pressure regulating valve
(pressure regulator) must be installed in the gas supply line to reduce pressure to this
appliance. See Figure 3-2.

Gas Supply Line Requirements
The Installer/Owner is responsible for furnishing and installing gas supply lines, valves,
regulators, and accessories.
When installing gas supply lines and accessories, observe the following:
a.
Refer to Figure 3-2 for the recommended layout of the gas supply lines.
b.
Use non-hardening pipe thread sealant resistant to LP gas.
c.
The ¾” NPT gas inlet is on the bottom of the 24CGA10. See Figure 3-2
d.
Install main manual shut off valve between the gas supply and the appliance. See Figure 3-2.
This main manual shut off valve is called the “Main Manual Gas Valve.”
e.
Install a sediment trap (drip leg) in gas supply line. See Figure 3-2.
3.
Test Gas Supply Lines
a.
Check all connections for proper tightness.
b.
